My 95 ram has a 5.9l with a high performance motor in it. It also has a 5 speed manual transmission. I've replaced the battery, crank sensor, MAP, IAC, TPS, ASD relay and did the fuel pump this morning. It was the origional 95' pump. Truck runs stupid strong.

The issue I have is when I'm coming to a stop the truck will idle too low and die sometimes. It also does it when I rev the truck up at rest and it will drop low and die sometimes. I have good fuel pressure at the rail. All sensors except the MAP sensor has been through the appropriate drive cycle.

I don't have any codes. Truck has new spark plugs and air filter as well. I believe the plug wires and coil are stock and might be origional to the truck I need to look. I need to change the spark plug wires anyway but I don't think that's the culprit. Any help is appreciated.


******* I fixed it just now. Cruise wasn't working so I figured I'd spend some time looking into it. The small hose from the servo under battery tray was broke in 2 and hidden by the sheath it's stuffed into over the motor. Fixed it and she idles correctly and cruise works. It was a minor vacuum leak causing the issue. Thought I'd leave this here for others if they have similar problems. **********

 

Check the distributor cap and rotor as well.... Have you cleaned the throttle body? IAC well likes to get all gunked up, and PCM has a hard time controlling idle.

 

I appreciate the suggestions. I have a new cap and rotor on it. I cleaned the throttle body when i assembled the motor thoroughly. I put the fix for the issue I had in my origional post and left it so others searching might find it useful.

 

Gotta love the cheap fixes.
